I'm just gonna throw this question out there and see what responses I get.

So if someone was performing their first head swap but could only afford a clean bench or a great precision tool made by HDD Surgery for swapping heads which would you recommend they buy to give them the greater chance of success? The clean bench or the HDD Surgery Tool?

I think that lcoughey gave pretty good answer. Head replacement tools and clean cabinets are two different things which can't be compared and both are pretty important for the DR business. However, we are hoping that soon (during this year) we will have our own Horizontal Laminar Flow Cabinet in offer (check https://www.youtube.com/watch?v=BjqkyIcqyuo). So, the plan is that you will be in position to buy both things under HddSurgery brand.

About price of our tools. There are reasons which stand behind their price. Costs of development, CAD modeling, technical drafting, prototype making, testing, production in high tolerances, having adequate machine park (which satisfies such tolerances) and corresponding cutting, shaping, fixing and support tools, making support documentation, quality control again and again, marketing, etc... However, after all procedures are fulfilled I think that we get tools of high quality and the tools which our colleagues evaluate as the best on the market. That's our greatest satisfaction and motivation to continue with good work.

there is some details of a project to build your own on here, and you can probably get away with not building it as good as Larry did.

Should not compromise on a clean environment.

that goes for everything that has to do with DR.I tell to my guys Data recovery is a process of simple steps that need to be done in precise order.Everyone can remove a screw or put a head change tool, but if you want to try a short cut it is dangerous.No mater if you change heads with papers, open drive on table, copy data and no clone etc etc etc....But life is not black and white, 99% of companies did not start with clean room and original pc3k...But good ones have all they need after some time

Can you give me ETA and approx cost of your bench? Mine is starting to play up (motor struggles to start up from cold, so I have to hit it!), typically just after I've paid £400 for a service and re-certification!

if it was up to me, I would get a the bench first. Tools for any drive with external parking ramp are a luxury. Not saying you shouldn't get it, but lets be honest you can use many things to space out the heads and prevent them from touching on a passport (some very very inexpensive things). However, without the laminar flow, you will most likely contaminate the top disk out, and 20-30 minutes into the imaging process (if your headswap is success) you will begin to hear noises...

I agree that both clean hood and tools are useful, but a head swap is not the kind of things that I would do for clients without prior training with waste drives.

You could purchase some tools to train yourself with waste drives, like drives with bad sectors abandoned by past customers after a successful DR, being aware that these drives may crash, because of the contamination when opened in a non cleanroom environment.

A laminar flow cabinet is not all in itself. The user behaviour is also an important to avoid contamination (smooth movements, surgical mask, gloves, pens without fibers, a.s.o.). I read one time a paper about how many particles does a surgeon emit during an operation (because of transpiration, scurf, ...) ; it was considerable. In real clean rooms (i.e. chambers), the operator is the main source of contamination if he doesn't wear special clothes, use non-fiber pens, a.s.o. Of course, probably less with a laminar flow cabinet, as apart from hands you don't have your body in it and the air flow can be strong.

You could train yourself with tools before buying or building a cumbersome clean bench.One possible problem however is the contamination of the tools themselves, when used in a non-clean environment. Maybe do exist tool decontamination techniques if you obtain a laminar cabinet afterwards.
